RAYON TRUCK.

Application filed September-14, 1928. Serial No Si)5,958.

This invention relates to stretchers for rayon silk.

It is the custom in handling skeins of rayon silkto support them on barsformed of aluminum tubes and to support the skein and bars assembled ona rack for the purpose of dry ing the rayon silk. The rack on which thealuminum bars have uniformly heretofore been supported have been made ofiron or some other similar material that would cause the aluminum skeinbars to become roughened and damage the rayon silk which came in contactwith the roughened places.

It is the purpose of this invention to provide a rack for the support ofthe skein bars in such a way that the bars will not become lacerated andtorn so as to damage the threads supported thereby.

It is the particular object of this invention to provide a frame forsupportingthe aluminum bars carrying the skeins of thread on which thereare provided supplemental cushion members made of soft and yieldingmaterial to immediately support the aluminum skein bars.

This is accomplished by providing the frame bars with a cushion surfaceof some other material than steel or iron. The other material used maybe aluminum, copper, brass or fibrous material formed in such a way asto form retaining means for the skein bars.

For the purpose of illustration there is presented herewith in thedrawings a preferred embodiment of this invention, which is shown by wayof illustration and to which the in vention is not intended to belimited.

Fig. 1 is a side view of atruck showing a plurality of means forsupporting and stretching skeins of rayon silk.

Fig. 2 is an end view with part of the operating means broken away.

Fig. 6 is a view showing one end of one of the cushion bars.

Fig. 7 is a View showing one of the skeins of thread and its skein bars.

Fig. 8 is a section on line 88 of Fig. 1. The device which is thesubject matter of shape and has extending upwardly therefrom at eachcorner upright posts indicated by the numeral 3, which are adapted tosupport the stretching and supporting means for the skeins o-f rayonsilk thread.

E Xtending across the upper ends of the upright post at each end of thetruck is a cross beam or bar indicated by thenumeral 4, which tends tohold the upper ends of the posts.

There are shown inthis drawing two .sets of stretching and holding meansfor the skeins of thread. Each set is composed of similar partslocatedon each side of the frame. The stretching means is composedessentially of two bars extending longitudinally over the truck frame oneach side of the truck. The upper bar is fixed to the frame and isindicated by the numeral 5. These barsare attached to the uprights ofposts 3 by means of bolts or rivets indicated by the numeral 6. y

Associated with each fixed stretcher bar is a movable bar indicated bynumeral 7, which is supported beneath the fixed bar and guided 7 inslots formed by the guide bars 8 and the uprights 3. .Just beneath eachone of the fixed bars and attached to the upright post 3 are brackets 9,which have extending therefrom ears indicated'bythe numeral 10 by whichthe brackets are attached to the up right posts. The lower ear of eachof these brackets serve to space the guide bar 8 from the upright forthe accommodation of the movable stretcher bars. The lower ends of theguide bars 8 are attached to the upright by means of rivets 11.

It is understood that the guide bars 8 pro? vide guiding slots for bothupper and lower movable stretcher bars. There are two sets of thebrackets 9, each having a bracket attached to each one of the uprights.I

In each of the side pairs of brackets there extends a hand wheel shaftindicated by the numeral 12, which is locate the brackets Ill? 9 so asto have up and down movement there in. On one end of each of the handwheel shafts on one side of the frame is a hand wheel indicated by thenumeral 13, while on the other end of each of the four hand wheel shaftsis a sprocket wheel indicated bynumeral 14. Connecting the two uppersprocket wheels and the two lower sprocket wheels are sprocket chainsindicated by the numeral 15. By means of this sprocket wheel and chainconstruction each shaft of the upper set or the lower set of stretchingmembers may be operated by turning one of the hand wheels 18. Each ofthe hand wheel shafts are threadec as indicated by the numeral 16 andreceive thereon in threaded relation therewith nuts 17 stretcher bar.

7 Extending from each side of the nut are ears 18 to each of which ispivotally attached 7 attached to the stretcher bars 5 or to thestretcher bars 7 The hand wheel shaft is located between a fixed bar anda movable bar and has a toggle connection therewith by means of the nuts17 and the links 19 by which the stretcher bars may be moved to or fromeachother. Each end of the hand wheel shaft has at least two screwthread sections in which the threads are in different directions so thatin the turning of the shaft the nuts thereon will move toward or fromeach other. hen the nuts are caused to move toward each other thestretcher bars are sep arated and when they are caused to move from eachother the stretcher bars are made to approach each other.

The stretcher bars 5 and 7 are composed of such material assteel or ironand are adapted to have strength and rigidity. For the purpose ofproviding a soft and smooth surface for receiving and carrying the skeinbars there is provided a cushion bar or a series of cushion barsindicated by the numeral 20. These bars may be made in section and areshown here as composed of 6 sections for each These cushion sections areattached to the stretcher bars by means of rivets or bolts indicated bythe numeral 21. The bearing surface these cushion bars is scallopedorserrated in form," as at 22, PTO".

viding cavities in which the skein bars 23 may rest.

This device is used in connection with skeins of thread'24c which issupported by the skein bars. There are two bars for each skein ofthread. One pair is supported by the upper stretcher bar while the otherpair is beneath the movable stretcher bar and is adapted to seat in oneof the notches therein. lVhen the proper number of skeins and the skeinbars have been assembled on the stretching device the hand wheel isrotated so as to bring the nuts on each part of the hand wheel shaft toward each other, thereby spreading the stretcher bars apartandstretching the rayon silk carried thereby on the skein bars. \Vhen therayon silk has been. thus assembled and properly tensed the truck withthe rayon silk thereon may be conveyed by the rollers to any suitableplace for drying or other purpose. It has been found in actual practicethat this stretching device with the cushion bars is very effective inthat it does not cause the skein bars to become lacerated or roughenedso that the silk is damaged.

Having thus described my invention, what I wish to protect by LettersPatent and claim as new, is set down in the following claims:
